Abstract— The logistics business is expected to soar significantly, for which will reach 30 percent by 2020, driven by the growth of transaction of e-commerce. This growth, indeed, requires an apparent concern from the transporter logistics to continuously enhance their performance. On the other hand, the performance of logistics transporters will provide a positive contribution to the increase of LPI (Logistics Performance Index) score of Indonesia. Thus, the development of performance measurement systems is necessary to maintain the competitiveness level of logistic actors. This study provides a comprehensive overview of performance measurement systems in regard to the 3PL (third party logistics) companies. The goal of this study is to develop such a conceptual framework that portrays the essential elements necessary to take into account when implementing performance monitoring system to the 3PL companies. The conceptual framework is established using grounded-theory approach which comprises of four main steps: collecting and mapping data sources, categorizing the data, identifying and naming concepts, and establishing a conceptual model. The framework itself, is constructed into two main stages: 1) developing KPIs, 2) measuring the performance. To exhibit the applicability of the proposed approach, a numerical experiment is provided. This research has two main contributions. First, the study fills the theoretical gap pertaining to the concept of performance assessment systems in case of 3PL companies. Second, in practical view the proposed conceptual framework contributes to the academia by describing the basis of establishing performance monitoring as well as to the practitioners who wish to better measure performance in the transporter logistics.

Abstract— Traditional cost accounting (TCA) is no longer reflecting the current economic reality due to distorted information about the profitability of their orders, products and customers. A new costing method is required to overcome the shortcoming of TCA in the era of rapidly increasing product complexity and diversification. The aim of this work is to apply the method of activity-based costing (ABC) on the inductor component for better accuracy. The work begins by collecting data at electronic industry located at Pahang, Malaysia and the product selected is inductor component. ABC focuses on the costs inherent in the activity -based products to produce, distribute or support the products concerned. Through the method, the work successfully gathered the time spent by operator to complete the task given. The largest time spent is at workstation 1 with 92.12% while the smallest at workstation 2,7, 8 and 14 with 0.1727% respectively. The highest cost of capacity supplied is drum core winding with epoxy activity with MYR 5,869,250.40 and the amount of material used is assigned as the cost driver. As the demand quantity of the product is increase by 10%, the total cost of production is predicted to be MYR 6,365,159.18 while the product cost per unit is MYR 1.50.

Elangperdana Tire Industry (PT. EPTI) is one of the manufacturers engaged in the manufacture of car tires. The problem faced by the company is the actual production time is not suitable and longer than the existing production time target. The average actual production time is 32 days while the average production time target is 30 days, this is due to the accumulation of material at several work stations. Problems in the production line are the cause of the production line obstruction which results in bottlenecks. In this study, improvements were made to the production line caused by the accumulation of material at some of these work stations. The object of research examined in this Final Project is the production floor of PT. Elangperdana Tire Industry. The purpose of this study was to design a production floor simulation model of PT. Elangperdana Tire Indusry uses the Theory of Constraint method to minimize production time at PT. Elangperdana Tire Industry. The initial stage in analyzing the production floor is by making direct observations to the production floor and making a process flow map to determine the initial conditions of the production floor. The next stage is to design the initial production floor simulation model and verify and validate the simulation model. Then the demand request is used to be used as the number of production targets in the proposed simulation. Furthermore, the improvement of the production floor uses the Theory of Constarint method to determine the classification of work stations classified as bottlenecks and not bottlenecks. There are three proposed improvements to this production floor, namely proposal 1 adding building machines, proposal 2 adding curing machines, and Proposal 3 a combination of Proposed 1 and Proposed 2.
